You got me 
@v_max
It is ridiculous but true that I made a bet with my elder brother that I would not submit any solution of any challenge until I get 100 in my college math exam. And our college examination is running now. It will be finished at 30 March. And the result will come in 5 April. So, I think I will miss March long Challenge, March Cook-off, March lunchtime etc. So, now I just try practice problem in CodeChef. Sorry to say, But I think you will see me again in April long challenge. Have a good day. Wish good luck to CodeChef Team.
Your best regards,
